A kind of brush cutter fan housing assembly is related to being applied to brush in a kind of afforestation electric tool as shown in Fig. 1 ~ Fig. 3
The fan housing assembly of machine improves structure comprising fan housing cabinet 7, clutch hub 1, casing 5 and outer cover 6 etc..
The fan housing cabinet 7 is made of metal material, interior to be equipped with along the perforative mounting hole 71 of axial line；Described
1 motion stops of clutch hub are mounted in 7 rear portion of fan housing cabinet, which is provided with the output shaft 3 protruded into fan housing cabinet 7, and the output shaft is logical
2 rotating support of bearing is crossed in fan housing cabinet 7, bearing snap spring 8 is respectively equipped in bearing two sides and fixation is installed, so that bearing
2 can stable support output shaft 3, then clutch hub 1 rotate when just will drive output shaft 3 rotate synchronously and output power.
The fan housing cabinet 7 is externally provided with outer cover 6, which is made of plastic material, and fan housing cabinet 7 is covered completely
Including conjunction, effect is: the long-term rotary work of drive shaft 3 can by a large amount of heat transfer to metal fan housing cabinet 7,
And plastic outer cover 6 can effectively completely cut off the heat on fan housing cabinet 7, play the role of heat-insulated protection, so as to avoid meaning
The generation of outer scald accident.
Shock-absorbing sleeve 4 in the fan housing cabinet 7 equipped with casing 5 and positioning sleeve outside casing；Wherein, casing 5 has
Across fan housing cabinet 7 and the outer end 51 of outer cover 6 is stretched out, the side of the outer end is equipped with bolt hooping structure 53, outer end
Outer wall is equipped with a location hole 52；5 outer circumference surface of casing being located in fan housing cabinet 7 is equipped with several positioning bars
54, which be made of the straight muscle 541 of the axial direction of several circumference uniform distributions and several radial ring muscle 542, this reality
Applying for example is the axial straight radial ring muscle 542 of muscle 541 and 3 that 4 circumference uniform distributions are equipped on 5 outer circumference surface of casing shown in Fig. 3；
The shock-absorbing sleeve 4 uses two rubber sleeves, and two rubber sleeves are sleeved on side by side outside casing 5, and on casing outer circumference surface
Several positioning bars 54 constitute be embedded in positioning；Meanwhile the shock-absorbing sleeve 4 of inner terminal, inner end, which is additionally provided with, is coated on the interior of casing 5
Disjunctor end ring 41 on end face.
After casing 5 and shock-absorbing sleeve 4 are installed in place in fan housing cabinet 7,5 inner end of casing can be by in fan housing cabinet 7
Shoulder positioning, 5 outer end of casing can be positioned by the casing circlip 9 for fixing in outer end, and disjunctor end ring 41 is simultaneously also as in casing 5
Resilient cushion between end and interior shoulder plays cushioning effect when brush cutter work.
When fan housing assembly as shown in Figure 1 and Figure 2 after the assembly is completed, in the front of fan housing assembly, that is, fan housing cabinet 7
The drive shaft 11 that front is equipped with the aluminum pipe 10 of inserting and is mounted in aluminum pipe.
Wherein, 10 rear end of aluminum pipe is inserted into as shown in Figure 4, Figure 5 in casing 5 until by positioning in fan housing cabinet 7, then
Realize that the inserting of 10 rear end of aluminum pipe fastens by bolt hooping structure 53, and a location hole on 5 outer end of casing, 51 outer wall
52 can be used for the inserting positioning of 10 rear end of aluminum pipe, therefore only need to be also provided with a corresponding location hole in the corresponding position on aluminum pipe 10
?；Therefore, after 10 rear end of aluminum pipe is inserted into casing 5, actually only it need to be positioned and be fastened by casing 5, aluminium can be completed
Connection inserting between pipe 10 and fan housing assembly, this plug-in mounting structure avoids traditional aluminum pipe 10 must be by four location holes
The trouble that just can be carried out fastening and positioning, on the basis of not weakening 10 use intensity of aluminum pipe, also with connecting, fastening is reliable, tears open
The use advantages such as dress replacement convenience, good damping effect, work concentricity stabilization.
The drive shaft 11 connection output shaft 3 as shown in Figure 4, and by the input of the power of output shaft after, then export to cutting
The workpiece of filling machine.
The above is only specific embodiment of the utility model, it should be appreciated by those skilled in the art that any and reality
